Other ideas:1. Remove and re-insert the Intel 750 SSD.2. If you should have inserted a discrete graphics card, remove it and let the system use the iGPU instead.3. If your current mainboard BIOS doesn't contain a suitable Intel GopDriver, insert it.

My Z68 Deluxe doesn't have a iGpu so that wont work. Not sure what good removing and reinserting will do but will try it.

Zitat von davidm71 im Beitrag #348The Deluxe has a d-GPU. There is no video output for the iGpu on the Deluxe version. The iGPU is used only for video co-processing. Cant use it for video hookup.

It has an iGPU as well. If you are running with CSM partially disabled (100% UEFI mode not possible with 5-series) then you won't be able to use EFI RST or GOP since your BIOS doesn't have such modules. That's offtopic as far as NVME is concerned but just saying...

Signed up to say thanks for the work; glad I stumbled onto it. I was able to boot into Windows 10 on a Samsung 950 Pro 512GB using an ASUS Sabertooth Z87 after modifying the BIOS (even though I know nothing about this). CrystalDiskMark shows the speeds I would expect from this drive.Procedure:1. Downloaded the latest Sabertooth Z87 BIOS (2103).2. Downloaded MMTool.3. Inserted the 3 ASUS Z97 modules downloaded from the link in the OP at Index 03 (saw this in a Z97 board BIOS).4. Flashed to the modified BIOS using USB Flashback5. Disconnected all SATA drives, turned on the computer, and saw the 950 Pro now listed as a boot device.6. Disabled Hardware Fast Boot and Fast Boot (unable to boot with these enabled).7. Installed Windows 10 onto the 950 Pro via another USB drive. [I was originally planning to upgrade to Windows 10 on this drive, so I hadn't installed it yet.]

Some notes: 1. My BIOS splash screen is now gone, so I don't see the TUF logo anymore, but it still says to press Delete or F2 to enter the BIOS. This screen pops up twice, first for around 3 seconds, and again for around 2 seconds.2. After the splash screen, the AMI screen always pops up saying the BIOS has invalid system information and to update the BIOS to resolve this (pressing F1 skips it).3. The Windows 10 boot logo appears briefly (1-2 seconds), disappears, and then reappears and boots fully into Windows without issues.

The trouble begins when you have a RAID 0 array as bootable MBR on the Intel RAID ROM as I did; while trying to install Win10 Pro 64bit using GPT in UEFI mode on the Samsung 950 Pro SSD ie in a mixed MBR /GPT dual boot environment. If you leave [Legacy OpROM first] it would find my Vertex RAID 0 array and the PCIe M.2 Samsung 950 Pro SSD would act as a regular SSD data partition. To boot the M.2 PCIe Samsung Pro SSD you need the UEFI mode. When I selected [UEFI first] the 2103 bios could find neither the Vertex RAID 0 array; as expected, as it was Legacy MBR, but it would prevent 'seeiing' the UEFI requiring Samsung 950 Pro. When I unhooked my SATA cables from the RAID 0 array and selected [UEFI first] boot option it would find the Samsung 950 Pro PCIe SSD and allow the install of the OS but not boot from it.

I then made a back up image of my original RAID 0 array and could install Win 10 Pro 64bit in the Vertex RAID 0 array and the M.2 Samsung 950 Pro SSD now both as GPT partitions.IE I had to convert the RAID 0 array from MBR to GPT, via UEFI USB selection, to load the UEFI bios 2103; it then correctly shows 2 (TWO) "Windows Boot Manager" loader options in UEFI mode:1. Samsung 950 Pro SSD2. OCZ Vertex RAID 0Now with both on the GPT/UEFI selection boot modality I can boot into either the OCZ Vertex RAID 0 or the Samsung 950 Pro SSD at a mouse click.

Also when I did the bios 2103 mod on the Asus Z87-Deluxe I lost one disk on a secondary hard disk RAID 0 array; and had to recover data from my second RAID 0 data partitionvia ReclaiMe RAID recovery software. As always back up your data before modding your bios....

Also, I was aware that ASUS was making the Hyper M.2 mini card but selected the Addonics as it had two extra slots for additional M.2 SSDs.It would appear that the Hyper M.2 mini card is bootable, while the Addonics card required the bios mod.

Thanks for your report, as it confirms ASUS Z87-Deluxe PCIe NVMe functionality so we now have two options to proceed.

Open question: I wonder if you can RAID0 two Asus Hyper M.2 cards in GPT/UEFI mode?

I've since asked ASUS to update their bios Advanced tab menu to include the UEFI selection "Intel Rapid Storage Technology" so one can set up RAID from within the UEFIenvironment as it clearly shows up in the Windows Boot Manager option. We'll see where that goes....

Thanks for that info; as obviously the Intel RAID ROM and the Option ROM on the Samsung were not playing nice in legacy mode, vying for boot supremacy on my system,but seem to happily co-exist in GPT/UEFI mode.

I thought of a solution to get the Intel 750 possibly able to boot. There is a boot loader called Ozmosis that you flash into the rom bios chip. Assuming you also include the Clover NVME Express driver in bios it may be possible to boot to a boot menu with the Intel 750 Selected. That is if installing Ozmosis doesn't brick the main board. I may try this when I get my new Z170 board and see what happens when I have nothing to lose anymore.
